3 Claims. (Cl. 24-205.14)

The present invention relates to new and novel improvements in a sliderfor a separable fastener and relates more particularly to an improvedconstruction of a slider and pull.

An object of the present invention is to provide a slider and a pullwhich can be assembled in a simple and in- Another object of theinvention is unit simultaneously by the attachment of the slider to apair of separable fastener stringers.

A further object of the present invention is to provide a slider andpull of this character having an automatic spring actuated lock element.

- Other novel features of the invention will be best understood from thefollowing description, when taken together with the accompanyingdrawing, in which certain embodiments of the invention are disclosedand, in which, the separate parts are designated by suitable referencecharacters in each of the views and, in which:

Fig. 1 is a plan view of one form of a slider pull assemblage which Iemploy With part of the construction broken away and in section.

Fig. 2 is a longitudinal sectional view through the structure, as shownin Fig. 1.

i Fig. 3 is a view similar to Fig. l of a modified form of construction,with part of the pull broken away; and

Fig. 4 is a longitudinal sectional view through the structure shown inFig. 3.

In Figs. 1 and 2 of the drawing, I have shown a slider body having topand bottom walls 11 and 12 joined by a connecting web 13 at the doublechannel end portion 14 of the body. The other single channel end portion15 of the body has inwardly extending flanges 16 and 17 on the walls 11and 12, respectively. The end portion 15 is considerably narrower thanthe central portion 18 of the body, thus producing what may be termedrecessed sides 19, in which side members 20 of a pull 21 are free tooperate. The side members 20 are within boundaries of the central wideportion 18 of the slider body, as clearly illustrated in Fig. 1 of thedrawing.

The pull 21 has a solid axle or pivot bar 22 which extends through thebody of the slider and integrally joins the sides 20 of the pull inrounded portions 23. The sides 20 of the pull may be united in acontracted or rounded end 24. Such a pull may be formed in one piece bydiecasting or the like.

The inner surface of the top wall 11 of the slider is provided with abearing recess 27 which extends transversely of the slider and receivesthe pivot bar or axle 'ice the scoops to move the slider along thestringers. The slider may also be provided with an enlarged recess 26'at the opposite side of the wall 11 to facilitate the use of anadditional lock element, similar to the element 25, if desired. However,the single element is shown in the present construction.

The slider body 10 is preferably diecast and the distance between theopposing faces of the flanges 16 and 17 is suflicient to permit thepivot bar or axle to pass between them in assembling the pull to theslider. After the pull has been put in place in the slider body, thedistance between the flanges 16 and 17 is then reduced by compressingthe slider body so that the pivot bar 22 can no longer pass betweenthem. If desired, the slider and pull may be assembled at the same timeas the slider is attached to the stringers of a separable fastener. Themethod of attaching sliders and pulls to separable fastener stringers inthis manner is more fully described and claimed in my copendingapplication Serial No. 295,244 filed June 24, 1952, for Method ofAssembling Sliders With Separable Fastener Stringers and in myapplication Serial No. 332,633, filed January 22, 1953, filedconcurrently herewith for Method of Assembling Sliders With Pulls andWith Separable Fastener Stringers to which reference may be made.

When the slider 10 and the pull 20 have been assembled and have beenattached to a separable fastener stringer, the pivot bar 22 of the pullwill rest on the tops of the scoops or elements on the stringers, asindicated by the dotted lines in Fig. 2, and will be held in the bearingrecess 27 in the slider thereby. This is made possible by the fact thatthe pivot bar 22 extends through the slider body and eliminates the needfor separate means to secure the pivot bar in the bearing recess.

In Figs. 3 and 4 of the drawings, I have shown at 28 a modified form ofslider body, having top and bottom walls 29 and 30 joined by aconnecting web 31. At 32 and 33 are shown inwardly extended flanges,generally similar to the flanges 16 and 17. It will also be apparentthat the general contour of the slider body 28 is the same as thatillustrated in Fig. 1, in other words, includes the recessed sides 34,providing the clearance for the side members 35 of a pull 36. The pull36 has a pivot bar 37 which extends transversely across the slider body28 and is movably supported in an angularly arranged hearing recess 38in the inner face of the top wall 29 of the slider body. The recess 38opens into the channel of the slider body and through the flanges 32, asseen at 39 in Fig. 4 of the drawing, to permit assemblage of the pull,as described above.

The top wall 29 of the slider body has a longitudinal recess 40 in whichis arranged an elongated lock element 41 pivoted to the wall 29 by apivot pin 42, the ends of which are shaped to conform to the contour ofthe wall 29, as will be apparent.

The element 41 has a downwardly and inwardly extending contracted scoopengaging part 43 which operates in an aperture 44 in the wall 29, whichagain opens into the channel of the slider body so that the part 43 canengage the scoops of a stringer in retaining the slider against movementthereon. The inwardly extending part 43 of the lock element includes anoutwardly extending stop member 45 which engages a cross-bar 46 at thecontracted end of the slider. This end of the slider has an aperture oropening 47 which opens into the aperture 44, as will clearly appear froma consideration of Fig. 4 of the drawing. The element 41 is normallyheld in its operative position, as shown in Fig. 4, by a coil spring 48arranged in an aperture 49 in the web portion 31 of the slider body, theaperture opening through the top wall 29 and the spring engages aninwardly extending nub or head 50 on the inner surface 3 51 of theelement 41 arranged directly above the aperture '43. 'The surface 51 isspaced sufliciently from the top wall 29 of the slider body to providemovement of the lock part 43 of the element out of engagement with thestringer scoops. The element 41 is moved into this inoperativeposition'by movement of the pivot'bar .37 of the pull from the positionshown in Fig. 4 .to the'outer extremity of the offset recess 38, as willclearly appear from a consideration of Fig. 4 of the drawing. This lastoperation is automatic in operation of the slider along the stringersthrough the medium of the pull, as in other devices of this type andkind.

With both forms of construction, it will appear that 'thepull isassembled within the recessed portion of the slider 'body and is free tomove in the slider body, but is retained against displacement therefromby reason of the .fact that the .pivot bar 22 or 37 is greater indiameter than the clearance between the flanges 16 and 17 or 32 and 33,respectively. This construction provides a very simple and, yet, strongand durable coupling of the pull with the ,slider body and theassemblagemay be accomplished 'by merely compressing the slider body aspreviously described.

With the structure shown in Figs. 3 and 4, it willbe understood that thelock element 41 is first attached to the top wall 29 of the slider bodybefore assemblage of the fingerpiece or pull and, by keeping the element41 withinboundaries of the top wall, pressure can be ap-v plied to thewall in the assemblage above referred to. It is preferred that theelement 41 hasa roundedportion 52 on its inner surface, seating upon aslightly rounded surface 53 on the wall 29, so as to facilitate the freeswinging movement of the element-41, while at the same time givingstrength to this element at the pivot portion thereof.

.Having fully described my invention, what I claim as new and desire tosecure by Letters Patent is:
